Bringing Back Color: Retouching Faded Furniture With Colored Light
In this article we summarize research conducted over the past 15 years aimed at understanding the original colors used in stained furniture. It is a synthesis of research, part of which is published, but this article also contains data from internal research reports. We present the results of chemical analysis and the outcome of reconstructions made based on historical recipes and degradation research. We used these findings to retouch furniture with colored light, using beamers controlled by computers, mapping software, and photogrammetry
Acceptance and adoption of biofortified crops in low- and middle-income countries
Biofortification of staple crops through conventional plant breeding, genetic engineering or agronomic approaches, is a promising strategy for increasing dietary nutrient density to improve human health. Successful implementation depends, amongst others, on willingness of consumers and farmers to accept the newly bred crop varieties
Understanding dyadic promoter-stakeholder relations in complex projects
In this study, we propose a Bilateral Double Motive framework of stakeholder cooperation in complex projects. The framework analyses and explains dyadic promoter-stakeholder relationships at a micro level by acknowledging both transactional and relational motives. We demonstrate the framework’s usefulness by illustrating its explanatory power in two instances of cooperation and two of non-cooperation within two health information technology projects. The study contributes to project management theory through its combined focus on transactional and relational motives. Further, the study contributes to practice by providing a tool for planning and evaluating cooperation in health Information Technology projects and similar complex multi-stakeholder environments
DARIS : a low-frequency distributed aperture array for radio astronomy in space
The frequency band below 30 MHz is one of the last unexplored bands in radio astronomy. This band is well suited for studying the early cosmos at high hydrogen redshifts, the so-called dark ages, extragalactic surveys, (extra) solar planetary bursts, and high energy particle physics. In addition, space research such as space weather tomography, are also areas of scientific interest. \ud

Due to ionospheric scintillation (below 30MHz) and its opaqueness (below 15MHz), earth-bound radio astronomy observations in these bands are either severely limited in sensitivity and spatial resolution or entirely impossible. A radio telescope in space obviously would not be hampered by the Earth's ionosphere. In the past, several (limited) studies have been conducted to explore possibilities for such an array in space. These studies considered aperture synthesis arrays in space, at the back-side of the Moon, or a satellite constellation operating in a coherent mode. \u
Variation in occupational exposure associated with musculoskeletal complaints:a cross-sectional study among professional bassists
Variation in occupational exposure is assumed to have a protective effect against the development of musculoskeletal complaints (MSC), but this common assumption is not strongly supported by the literature. Among musicians, who have a high prevalence of MSC, many play more than one type of instrument (multi-instrumentalism) for many hours a day. Since multi-instrumentalism implies greater variation in ergonomic load of specific musculoskeletal areas than mono-instrumentalism, musicians are a suitable study population to test whether the above assumption is true. To investigate in a sample of professional bass players whether multi-instrumentalists are less likely to have MSC than mono-instrumentalists. Participants were 141 professional and professional student double bassists and bass guitarists. Demographic, MSC and exposure characteristics were collected online with self-constructed and existing questionnaires. Logistic regression analysis was used to test the association between multi- versus mono-instrumentalism and MSC, adjusted for confounders. The prevalence of having MSC in the neck, back, right shoulder area and both wrist areas did not differ significantly between the two groups. Further analysis revealed that the likelihood of having MSC in the left shoulder area was higher in multi-instrumentalists compared to mono-instrumentalists (Odds ratio 0.30, 95% CI 0.119-0.753, p = 0.010). In this sample of professional bass players, no protective effect of multi-instrumentalism against MSC was found. Multi-instrumentalism was associated with a higher prevalence of MSC in the left shoulder. This result challenges theoretical and clinical assumptions in occupational and pain medicine
Co-Creation of a Multi-Component Health Literacy Intervention Targeting Both Patients with Mild to Severe Chronic Kidney Disease and Health Care Professionals
Limited health literacy (LHL) is common in chronic kidney disease (CKD) patients and frequently associated with worse self-management. Multi-component interventions targeted at patients and healthcare professionals (HCPs) are recommended, but evidence is limited. Therefore, this study aims to determine the objectives and strategies of such an intervention, and to develop, produce and evaluate it. For this purpose, we included CKD patients with LHL (n = 19), HCPs (n = 15), educators (n = 3) and students (n = 4) from general practices, nephrology clinics and universities in an Intervention Mapping (IM) process. The determined intervention objectives especially address the patients’ competences in maintaining self-management in the long term, and communication competences of patients and HCPs. Patients preferred visual strategies and strategies supporting discussion of needs and barriers during consultations to written and digital strategies. Moreover, they preferred an individual approach to group meetings. We produced a four-component intervention, consisting of a visually attractive website and topic-based brochures, consultation cards for patients, and training on LHL for HCPs. Evaluation revealed that the intervention was useful, comprehensible and fitting for patients’ needs. Healthcare organizations need to use visual strategies more in patient education, be careful with digitalization and group meetings, and train HCPs to improve care for patients with LHL. Large-scale research on the effectiveness of similar HL interventions is needed
AdS Duals of Matrix Strings
We review recent work on the holographic duals of type II and heterotic
matrix string theories described by warped AdS_3 supergravities. In particular,
we compute the spectra of Kaluza-Klein primaries for type I, II supergravities
on warped AdS_3xS^7 and match them with the primary operators in the dual
two-dimensional gauge theories. The presence of non-trivial warp factors and
dilaton profiles requires a modification of the familiar dictionary between
masses and ``scaling'' dimensions of fields and operators. We present these
modifications for the general case of domain wall/QFT correspondences between
supergravities on warped AdS_{d+1}xS^q geometries and super Yang-Mills theories
with 16 supercharges.Comment: 7 pages, Proceedings of the RTN workshop ``The quantum structure of
